ObjectTimeline never took the settled-schema gate — 2 find calls and a second paint per load, the last unconverted member of #6482 / #7225

Filed unassigned by the domain:ui execution seat while working #7828 (PR #7892). Not fixed there on purpose: that card's file surface is two test fixtures, and its ruling is explicitly Clause-② = no — no runtime code.

Duplicate check run before filing, with a control that fires: a repo-scoped listing of all 400 open issues, grepped locally (/search/* answers 403 for this seat). The control returned on-topic hits — #7232 (ObjectGantt's schema-resolution exits that never settle), #7233, #7237, and #7429 ($expand ungated at seven buildExpandFields sites, timeline among them) — so the absence of a match is a reading rather than a broken query. #7429 is the neighbouring but distinct concern: it is about the FLS gate on the expand set, not about when the record query fires.

The observation

ObjectTimeline is the one record view that never took objectui#6482 / objectui#7225's settled-schema gate. It still carries the pre-#7225 shape:

packages/plugin-timeline/src/ObjectTimeline.tsx:176 — a local useState for the object definition, not the shared useSettledSchema;
packages/plugin-timeline/src/ObjectTimeline.tsx:254 — objectDef is in the record-fetch effect's dependency array, so the effect runs once with the definition unresolved and again once it lands.

That is exactly the shape objectui#7225 ask 2 removed from ObjectGantt, whose own code comment describes the cost it was removing: "2 find calls and 1 getObjectSchema per load", and, whenever the metadata read is the slower of the two, "the user sees the full THREE-STEP PAINT — raw foreign-key ids, back to the loading placeholder, then the expanded rows". ObjectCalendar took the same gate at objectui#6453.

Measured, not inferred

Instrumented mock renderer counting writes per single mount, getObjectSchema held by a fixed delay, all three components in one vitest run (this is the trace PR #7892 produced while establishing that the two sibling fixtures do not paint twice):

component	hold	paints when the arity predicate goes green	paints total	late writes
`ObjectTimeline`	+25ms	1	4	3
`ObjectTimeline`	unperturbed	1	1	0
`ObjectCalendar`	+0 / +25 / +100ms	1	1	0
`ObjectGantt`	+0 / +25 / +100ms	1	1	0

The two gated components' first paint arrives only after the metadata read — their measured paint time tracks the hold (calendar 34ms at +25, 104ms at +100; gantt 31ms and 114ms) — and nothing follows it. ObjectTimeline paints at 15ms under a 25ms hold, i.e. before the metadata lands, and then writes three more times.

The container settles the two reads together by default, which is why the unperturbed row shows nothing and why this is invisible in ordinary local runs. A real backend with a cold MetadataCache is the profile objectui#6482's per-component standard names as the one where gating pays.

Why it is worth recording

It is the last unconverted member of a set that was deliberately converged: ObjectKanban, ObjectView, ObjectCalendar and ObjectTree were named in objectui#6482, ObjectGantt was ask 2 of objectui#7225. ObjectTimeline was in neither list, and nothing marks it as a deliberate exclusion.

Second-order, and the reason the measurement exists at all: this double paint is precisely what made objectui#7466's ladder fixture intermittently red, and it is why the timeline fixture needs harness guards that its two siblings — measured, in PR #7892 — do not need for any reason of their own.

⚠️ Not claimed here: that any user has reported this, or that the expand set is wrong. The $expand gap at this site is #7429's, and this card does not overlap it.

这张卡的证据已经存在，不要重新发明

它是 PR #7892（卡 #7828）建立同胞夹具不画两次时顺带产出的 trace，而且 ObjectTimeline 在那次测量里是阳性对照——它之所以是阳性，就是因为这个缺陷是真的。

组件            hold    判据变绿时的绘制  总绘制  late writes
ObjectTimeline  +25ms          1            4        3
ObjectTimeline  未扰动         1            1        0
ObjectCalendar  +0/+25/+100ms  1            1        0
ObjectGantt     +0/+25/+100ms  1            1        0

两个已门控组件的首绘时间跟着 hold 走（calendar +25 时 34ms、+100 时 104ms；gantt 31ms / 114ms），而 ObjectTimeline 在 25ms hold 下 15ms 就绘制了——早于元数据落地，随后又写三次。

交付物

采用 #7225 / #6482 已收敛的那套已结算 schema 门控（共享 hook），把 :176 的本地 useState 与 :254 依赖数组里的 objectDef 一起消掉。

⭐ ObjectGantt 是现成的工作样板（#7225 ask 2），ObjectCalendar 是另一个（#6453）。⛔ 不要设计第三种写法 —— 这个集合是被刻意收敛过的（#6482 点名了 ObjectKanban/ObjectView/ObjectCalendar/ObjectTree，#7225 ask 2 收了 ObjectGantt），ObjectTimeline 是最后一个未转换成员，而且没有任何东西把它标记为有意的排除。

⛔⛔ 证据要求：不许用「测试变绿了」当证据

本卡的缺陷在普通本地运行里不可见 —— 容器默认把两次读取一起结算，所以未扰动那一行什么都不显示。⛔ 一次没有 hold 的绿色运行零信息。

必须复现 PR #7892 的测量形状（它就在那张卡的落地记录里）：把 getObjectSchema held 固定毫秒，数单次挂载的写入次数。给出：

改前：ObjectTimeline 在 hold 下 1 次绘制 + N 次 late write（预期 N=3 @ +25ms，但以你的实测为准）；
改后：1 次绘制 + 0 次 late write，且首绘时间跟着 hold 走（这一条是门控生效的签名，⛔ 不是「碰巧没观察到」）；
阳性对照：同一批运行里带上 ObjectCalendar 或 ObjectGantt，它们改前改后都应是 1/0 —— ⭐ 让对照与被测在同一次 vitest run 里，这是 test(plugin-calendar,plugin-gantt): the colorField ladder fixtures name their own writer (objectui#7828) #7892 的做法，也是让读数可比的原因。

⚠️ #7892 的席位付过一次学费：较粗的网格在八档里只抓到一档，所有对照失败都落在 1–9 ms 窗口内。⛔ 如果你的仪器在某个 hold 上什么都没测到，加密网格，不要增加重复次数 —— 在窗口外重复一万次仍是零功率。

⚠️ 第二重收益，请一并测量并写进 PR

这个双绘制正是 #7466 那个阶梯夹具间歇性变红的原因，也是为什么 timeline 夹具需要那些守卫、而它两个同胞（#7892 已测）因自身原因并不需要。

⇒ 修好之后，timeline 夹具在 pre-#7521 harness 形状下还会不会红？ 到 1–9ms 窗口里去量。⚠️ 无论答案是什么都如实报：若仍会红，说明还有第二个机制；若不再红，那是本卡的第二个交付读数。⛔ 不要因此删除或放宽任何守卫 —— 守卫的价值不依赖于当前是否有活跃的触发源。

边界

⛔ 不动 packages/plugin-timeline/src/useTimelineTranslation.ts（finding(plugin-timeline/i18n): five timeline.relative.* defaults rows have no en key and no caller — invisible to every existing i18n gate #7874 / PR chore(plugin-timeline): retire the five dead timeline.relative.* default rows (objectui#7874) #7887 的面，在队列里）。
⛔ 不碰 $expand / FLS —— 那是 $expand is still ungated at SEVEN more buildExpandFields call sites — kanban, tree, ObjectView, map, gallery, timeline and PagePreview, none of which passes a column list #7429 的面，卡面已明确本卡不与之重叠。
⛔ 不动 ObjectGantt / ObjectCalendar（它们已转换）。
changeset： plugin-timeline 是已发布包且改 src/ ⇒ 机械地欠一份，而且这是真实的用户可见修复（少一次网络往返、少一次三步绘制）⇒ 大概率是 patch 而非空 frontmatter。⛔ 不要用我这句猜测：跑 node scripts/check-changeset-presence.mjs，以判词为准并逐字贴出。（今天检查器已五次推翻关于 changeset 的推理，其中两次是本席的。）
Clause-② = no：不加 schema 键、不动 zod、不改任何校验的接受/拒绝行为、不动任何 gate 的判据或扫描总体 —— 只改一个组件内部的抓取时序。若这个判断错了，停下报回。

  "summary": "Confirmed the card's premise on origin/main and implemented it. ObjectTimeline.tsx:176's local `useState` for the object definition and its hand-written metadata effect are replaced by the shared `useSettledSchema` (@object-ui/react); the record-fetch effect at :254 now gates on that resolution instead of re-running when the definition lands, and `objectDefReady` joins `objectDef` in its dependency array (the two are one mechanism). Follows ObjectGantt (objectui#7225 ask 2) and ObjectCalendar (objectui#6453); no third shape. Two deliberate departures from those two, both documented in the source and the PR: the metadata read is NOT disabled for an authored-items timeline (this component reads the definition's fields for option colours and labels on that path, where no query is issued), and the gate key is `schema.objectName` \u2014 the object the record query itself names \u2014 rather than `resolveRecordSourceObjectName`, since this component resolves no `data` block. Clause-2 holds: internal fetch sequencing only, no schema key, no zod, no validator behaviour, no gate predicate or scan population. Changeset scored `patch` per the checker's verdict, quoted verbatim in the PR. New pin: ObjectTimeline.fetchGate-7895.test.tsx (6 cases).",

BEFORE \u2014 ObjectTimeline: 2 find calls, expand sets [null, ['owner']]; 1 paint at the arity predicate plus 3 late writes at every hold from +3ms up (1 late write at +2, none at +0/+1 \u2014 the refined grid located the lower edge); first paint flat at 3-7 ms whatever the hold, i.e. BEFORE the metadata. AFTER \u2014 1 find carrying ['owner']; 1 paint, 0 late writes; first paint TRACKS the hold: 8ms at +3, 19ms at +10, 30ms at +25, 55ms at +50, 105ms at +100. Controls read 1 paint / 0 late writes / 1 expanded find at every hold before AND after, first paint tracking the hold throughout (calendar 29ms at +25, 103ms at +100; gantt 29ms / 104ms). SECOND-ORDER (the objectui#7466 question): pre-#7521 harness shape \u2014 module global, arity-only predicate, no unmount, re-read of the global \u2014 two renders inside one `it`, holds 1..9ms, 10 reps per hold: fix reverted 40 fail / 90 runs (signature: second=['#abc'] where ['#123456'] was authored); fix in place 0 fail / 90 runs. ANSWER: it no longer reddens in that window. No guard was deleted or relaxed; ObjectTimeline.colorFieldLadder-7243.test.tsx is untouched. REVERSE VERIFICATION: fix committed FIRST, then `git checkout d9580f4647f4a0f3f44d51ce6d4752e52f1fed08 -- PATH` (a pinned commit, never a moving remote-tracking name), mutation CONFIRMED ON DISK by blob hash (on-disk 1b4575de... == the base blob, against HEAD's 6eae2ef8...) plus grep counts (useSettledSchema 0, setObjectDef 2); restored with `git checkout HEAD -- ABSOLUTE_PATH` under a trap, restoration proved by an EMPTY `git diff HEAD` and a blob hash matching HEAD, not by an exit code. NO REBUILD LEG APPLIES and that is stated rather than omitted: the instrument imports './ObjectTimeline' relatively and the root vitest alias table points every @object-ui/* specifier at src/, so no dist is on the resolution path for any leg. With the fix reverted the new pin reads 4 failed / 2 passed \u2014 predicted 2 red, observed 4; the extra two are the held-paint case (the mechanism) and the rejecting-read case (the replaced effect logged console.warn with its own wording where the hook logs '[useSettledSchema]' through console.error). Direction as predicted, magnitude higher, reported not adjusted. GATES, all re-run AFTER the final commit on the pushed SHA aca81f48a with `git diff HEAD` empty: `pnpm exec vitest run packages/plugin-timeline/` -> 24 files / 297 tests passed (23 pre-existing files plus the new pin; the pin's 6 cases verified by name in a verbose run). `pnpm --filter @object-ui/plugin-timeline run type-check` -> EXIT=0 (tsc --noEmit && tsc -p tsconfig.test.json); NOT vacuous \u2014 `tsc -p tsconfig.test.json --listFiles` names both src/ObjectTimeline.tsx and src/ObjectTimeline.fetchGate-7895.test.tsx (1 hit each). Dependency closure built first with `pnpm --workspace-concurrency=2 --filter '@object-ui/plugin-timeline^...' build` (EXIT=0), so the type-check is not the stale-dist trap. `pnpm --filter @object-ui/plugin-timeline run lint` -> EXIT=0, 0 errors / 109 pre-existing warnings. check-changeset-presence EXIT=0 verdict quoted verbatim in the PR; check-changeset-no-major, check-changeset-overwrite, check-changeset-fixed, check-control-bytes, check-vi-mock-specifiers, check-vi-mock-inherit, check-unreferenced-sources, check-lint-coverage, check-type-check-coverage, check-package-self-import, check-i18n-call-site-keys, check-i18n-dead-keys, check-side-effects-array, check-entry-guard -> all EXIT=0. check-governed-queue-guard --test on all three changed paths -> 'NOT GOVERNED - 3 path(s) checked against 5 governed surface(s); none matched'.

Neither is in the family derived from these paths and CI builds before running them. Every exit code captured by redirecting to a file FIRST, never read through a pipe.
